LNG (Liquefied Natural Gas) mobile filling vehicle with filling structure

Abstract

The invention discloses a LNG (Liquefied Natural Gas) mobile filling vehicle with a filling structure and belongs to the technical field of low-temperature liquid mobile filling, storing and transporting vehicles. The LNG mobile filling vehicle with the filling structure comprises a tractor vehicle, a LNG low-temperature storage tank, a tank bottom type filling mechanism, a special semi-trailer chassis walking mechanism, a rear operation pipeline and a bin body, wherein the LNG low-temperature storage tank, the tank bottom type filling mechanism, the rear operation pipeline and the bin body are mounted on the special semi-trailer chassis walking mechanism so as to form a low-temperature liquid semi-trailer; the low-temperature liquid semi-trailer is suspended on a traction seat of a traction 1 by means of a traction pin so as to form a whole vehicle. The LNG mobile filling vehicle with the filling structure not only has the function of stopping in any place at any time for independently filling LNG for LNG vehicles and dual-fuel vehicles, but also has the transportation function of transporting LNG by the road; meanwhile, the LNG mobile filling vehicle with the filling structure not only has the function of stopping in a fixed place at any time for independently filling LNG for LNG vehicles and dual-fuel vehicles, but also has the transportation function of transporting LNG by the road. Due to the lightweight design of the whole vehicle, the whole vehicle is relatively light in weight and relatively large in maximum filling weight or filling quantity.

Description

technical field [0001] The invention belongs to the technical field of low-temperature liquid mobile filling and storage and transportation vehicles, in particular to a mobile LNG filling vehicle with filling structure, and a low-temperature liquid vehicle with LNG (liquefied natural gas) filling function. Background technique [0002] Liquefied natural gas is an efficient and clean energy and the most ideal fuel for protecting the environment. With the world's energy crisis and environmental problems becoming more and more prominent, on the one hand, the shortage of oil resources and the increase in car ownership have exacerbated the contradiction of energy shortage; The main cause of smoggy weather. Therefore, the country has introduced policies to support and promote the wide application of natural gas. The technology of new energy vehicles represented by LNG vehicles is mature and the market demand is strong. Liquefied natural gas (LNG) vehicles have high energy storage ...

AI Technical Summary

Problems solved by technology

With the popularization and application of liquefied natural gas (LNG) vehicles and dual-fuel co-combustion technology, there is an urgent need for convenient and mature filling facilities for them. However, fixed LNG filling stations have large investment, long construction period and difficult qualification approval. Prominent Restricting Factors for Popularization of Natural Gas (LNG) Vehicles
